Seagate Computer Components: IDE PCB | sku-520252543

This Seagate Computer Components listing is for the hard drive circuit board (PCB or logic board) only; no hard drive is included. Board identifiers are ST3320820A, 9BJ03G-500, 3.AAC and 100436212 E. The board received may differ slightly from the photo. It is intended for data recovery and hard drive repair. Before buying, use the hard drive diagnostics guide to check whether a PCB replacement will resolve the problem, and confirm compatibility with the Donor Matching Guide. Most Seagate IDE 3.5 PCBs store unique information in a ROM chip that the drive needs to operate. The chip or its data must be transferred or reprogrammed onto the replacement board; a local computer repair technician can typically transfer the chip if that is possible. Orders of $60 or more include an adaptation service that transfers the ROM chip or programs the replacement board with the correct ROM data. Review the PCB Replacement Guide before attempting the swap yourself. If a simple swap does not fix the drive, a PCB Replacement Service is also offered; see the Adaptation Service page for details.
